thermal: cpu_cooling: initialize 'cpufreq_val' on registration
There is no point checking for validity of 'cpufreq_val' from cpufreq_thermal_notifier() every time the routine is called. Its guaranteed to be 0 on the first call but will be valid otherwise. Lets update it once while the device registers. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
